Topic summary
Adding an Add to Cart button on Prestige collection pages and hiding it for sold‑out items. The store uses Shopify’s Prestige theme; code was added to product-item.liquid to show the button on collection cards.
Key fix implemented:
- Wrapped the button in a Liquid condition using product.available to hide it for sold‑out/unavailable products. The original poster confirmed this resolved the visibility issue.
Technical notes:
- Liquid is Shopify’s templating language. product.available checks overall product availability; previously, only button styling changed based on a variant’s availability, not button visibility.
New, related issue raised by another participant:
- Button shows on collection pages but only opens the cart drawer without adding the product. They also need a way for customers to choose variants (e.g., size/color) in a “quick add” on collection cards. This typically requires additional JavaScript to add the selected variant to cart and UI for variant selection.
Other input:
- A YouTube tutorial link was shared as a general resource for restoring Add to Cart on collection pages.
Status:
- Original visibility problem resolved. Variant selection and add-to-cart action from collection cards remain open/unresolved.
